MACINE FOR IKOLDING OR. BENBING SHOE-SGLES.

Patented sept. i5, 1914.

Application led December' 10, 1909. Serial No. 532,307.

To all 'whom t may concern.'

Be it known that I, WILLIAM C. MEYER, a citizen of the United States, residing at Boston, in the county of Suffolk and StateV Y SELIBB.

v being suitably formed to mold Prior to the operation of lasting a turn shoe it is customary to bend down the margin of the sole in order that it may be more conveniently lasted and sewed. This operation is commonly performed by a machine provided with two rollers which are rotated to feed the work, and' which engage the op` posite sides of the sole margin, these rollers' or bend the material of the sole to the required form.

The present invention relates to machines of the type above described, and the object v of the invention is to improve the structure, arrangement and mode of operation of certain parts of such a machine.

With the above object in view, a feature of the invention relates to improved provisions for adjustment of certain parts of the machine.

Other features of the invention consist in certain improved constructions, combinations and arrangements of parts hereinafter described and claimed, the advantages ofvr which will be obvious to those skilled in the art from the following description.

Y In the accompanying drawings, which illustrate the preferred embodiment of my invention, Figure 1 isa side elevation of a turn `sole molding or bending machine; Fig.

2 is a front elevation of the machine; Fig. 3 is a rear elevation of the machine; Fig. 4 is a sectional elevation of the operative instrumentalities of the machine; Fig. 5 is an enlarged detail view in front elevation, showing the upper roll and the work guide.

The illustrated embodiment'of the invention is provided with an ,upper tool ork roll comprising three parts. The part 1 of this tool is provided with teeth or corrugations by which the feeding of the work is insured. The part 6 is cylindrical, and this part4 and the part -1 constitute together a generallyV cylindrical portion adapted to engage the upper surface of the body portion of the sole margin. The third part Bcf the upper roll is in the form of a flange or disk having a beveled and roughened surface adapted to engage the upper surface of the sole and to bend down. or mold the extreme marginal portion of thc-sole in thel usual manner. The upper roll is carried by a power shaft 4, being mounted on a screw 5 threaded into the kforward end of the shaft.' This screw, together with two adjusting nuts 7 which are threaded on the end of the shaft, constitute means for adjusting the upper 'roll axially, this adjustment being accomplished by rotating the nuts or the shaft until the roll is in proper position, and then' tightening the screw 5 to secure the parts of thek roll together in adjusted position. The shaft 4 is j ournaled in the frame 8 of the machine,

and is provided with a fast pulley 9 and a loose pulley 10, together with a belt shipper 11, by which the machine may be started and stopped when run by power. The ma- Y chine is also provided with a hand crank 13 connected with the shaft 4 byv gears 12,V so that the machine may be actuated by hand if desired. The lower roll '2 is of a form common in machines of this type, and it has the upper roll, to grip the bent margin of the sole. The lower roll is mounted upon an inclined shaft 14 which turns in awcasing 15 pivotally mounted at 16 on the frame of the machine. To permitthe lower roll to accommodate itself to variations in thickness in the work, and also to facilitate the introduction of the work between the rolls, provision is made for pivotal movement of the casing 15, by which the roll 2 is moved in a direction transverse to its axis and toward and from the upper roll. To this end a rod 18 is pivoted at 17 to the front of the casing 15, and this rod passes loosely through a lug 19 extending from the frame of the machine. A. compression spring 20 engages the lug 19 and an adjustable nut 21 on the rod 18, and this spring` tends constantly to hold theroll 2 up against the work.

Y rl`he vstop lscrew is adjustable so as to accommodate its opera- V'tion to rolls of different diameters.V

The upper roll alonemay be actuated, but l it is preferred to actuate both rolls in unison, and to this end bevel gears 35 and 36 Aare :mounted upon the shafts'l4 and 4, Vthese .gears lee-ing arranged to Vmesh so near tothe :pivot flrthat their operation is not inter- ,fered with by the pivotal movements of the :spect to the upper roll.

In addition to' the operative instrumen- .ftalities hereinbefore described, the machine is provided with a work guide 29 arranged #to engage the edge of the sole. This guide is mounted on a stem 30 which is carried in la v'sleeve l3l and is adjustably secured by a 'set screw 32. This arrangement permitsthe .work `guide to be'adjusted axially with re- The sleeve 3l is carried on a slide 33 which is vvertically adjustableion the frame 8, and is fixed in po -sitionby a screw 34 engaging an elongatedA opening inthe slide. This construction permits the guide to be adjusted transversely with respect to the upper roll. The two adjustments of the work guide together adapt 'it to coperate with rolls of different forms Aand sizes, and also permit the work guide 's -toHbe-adjusted to compensate for the axial adjustment of the upper Iroll hereinbefore described. By vthe axialy adjustment of the :upper roll, `in combination with the transf :verse adjustment ofthe lower roll, the maj -chine may be adjusted `to operate kupon a fsole :having a body of any thickness and a margin of "the same or any other thickness, :andthe 1machine is therefore adapted for use -on `awider variety. of work than a machine 'constructed without such provision for adjustment.

`My-'invention is not limited to the construction hereinbefore described and illustrated in the accompanying drawings, but

, :maybe-embodied in other forms within the `-natureiofthe invention and the scope of the following'claims. Y'
